CONCORD, N.H. (AP) — New Hampshire Attorney General Joseph Foster and State Police Colonel Robert Quinn say a second arrest has been made in the 2010 attack on a state prison inmate who died 16 months later as a result of his injuries.

Thirty-one-year-old William Edic — an inmate at the state prison in Concord — was charged Wednesday with second-degree murder in the death of 44-year-old Anthony Renzzulla.

Prosecutors last week charged 30-year-old Thomas Milton — also an inmate at the time — with second-degree murder. Both men also face charges of falsifying physical evidence and hinder prosecution.

Edic will be arraigned in Concord District Court on Thursday. Milton was arrested in Florida and faces extradition.
